IMPRQVEMBNT IN seres.

The Schedule referred to :h1 these Letters Patent and makingV part of the same.

To all whom 'it may concern:

Be it known that I, MARTN BnrGGs, of the city of' Rochester, in the county of Monroe, and State of -.New York, have invented a certain new and useful Improvement in Burglar-Proof Safes; and I do hereby declare that the following is a full and exact description thereof, reference being had to thcaccompanying drawings, making part of this specification', in which Figure 1 is a perspective view, and

Figure 2, a section of one side of the safe.

Like letters of reference indicate corresponding parts in both figures V.

' My invention consists in. constructing a safe of plates which present a uniform steel surface upon the outside, andiwhich are united by screws that enter the walls from the-interior, and extend but part way through the whole construction being such as to render the safe impenetrable to either drill or wedge, ashcreinvafter described.

The edges of the bands areroundcd, as shown at p,

to prevent chipping ofi' underthe action ot'. the sledge.

'lhis arrangement of the plates and'bands B C preseuts va smooth andiiush cxteriorsiu'iace, without rivct or screwreaching the outside, and having closely-- iitting seams, which will notallow the insertion ofV a wedge.

The angle-irons or boardsare connected together by nlortise-alnl-tenon joints m..

rlhe outer plates are what are known as.welded iron and steel plates,` composed of two layers, -respectively, of-iron and steel, `placed together flatwise, welded and-rolled or hannnered, thus vpresenting a steel idee on one side land1iron on thcother.

In my construction of the safe, the. steel is placed outward, 'and the safe thus presents, on the exterior, 'an entire and uniform. steel surface.

If dcsired,.the inner plating A may be used in the same way,1c1 'itinay bernadeof iron alone.`

v'I hespecial advantageslclaim in this construction Vin which the bolts and rivet-s great solidity, will cause such instrument to dull and break. It is thus impenetrable by any instrumentality that can be brought to bear upon it.

The securing ofthe screws upon the inside, and not extending through, prevents the drilling out of the same, as isv frequently done upon ordinary safes, pass through from-the outside instead of the inside.

I am aware that welded steel and iron lates have 'before been employed in the construction of safes, but located within thc walls, instead of on Vthe outside of the same.

In such case, Athe outside of the safe has been con-- stiucted simplyzof iron plating, which is easily cut and 'torn from place, and when this is done, the screws or bolts, which attach the outer tothe inner plating, are loosenedfand exposed, and can be driven in or drilled out, 'which gives a ready access to tools by which the interior of thesafe may he readily reached.

Alhis projection `of. the screws through the inner plating cannot lie-avoided, as the outer lmust be held .in place by it, and itfthe outer is "easily torn from place, the inner is necessarily'penetrable.

The only remedy is to make the outer platingA im-` penetrable at the start, which I accomplish yby'making asteel surface andavoiding'theiextension through of the screws or bolts.

What I claim as my invention, and desire rto secure by Letters Iateut, irs- A safe, consisting of the inner plates A, 'the outer panels B, screws a, and angle-irons O C, covering the angles of the sides and top and bottom', said irons be- -ing connected together by mortise-and-tenon joints,

the whole constructed and arranged as set forth.

In witness whereof, I, have hereunto signed .my name, in the presence of two subscribing witnesses.

Witnessess MARTIN BRIGGS.
